A homeless man was found dead on the porch of an abandoned Queens home Sunday morning, police said.

The 27-year-old was discovered with a head wound about 9 a.m. at the home on Lefferts Boulevard near 95th Avenue in South Richmond Hill, cops said.

He was declared dead on scene, authorities said.

Three people inside the home — two men, ages 25 and 22, and a 17-year-old woman — were taken into custody. Charges against them are pending, police said.

The city’s Medical Examiner will determine the man’s cause of death.
